LUBRICATING SYSTEM.

Specification of Letters Patent.

Patented J an. 3, 1911.

Application filed .Tune 14, 1909. Serial No. 501,907.

To all whom 'it may concern:

Be it known that I, LEON ALLEMAN, of Rochester, in the county of Beaver,State of Pennsylvania, have invented a certain new and usefulImprovement in Lubricating Systems, of which the following is a full,clear, and exact description.

The object of my invention is to provide a simple and inexpensivelubricating system for crank pins and the like; and it consistsprimarily in the utilization of centrifugal force in the conveying ofthe lubricant to the desired point of lubrication, as will behereinafter more fully set forth.

I shall now describe my invention so that others skilled in the art towhich it appertains may understand the same, referring to theaccompanying' drawing forming part of this specification and in which Ihave shown my invention as applied to the lubrication of the pin of acenter crank of a vertical engine. I do not, however, desire to limitmyself in this respect.

Figure 1 is a vertical sectional view through the crank casing of avertical engine showing my invention applied to the lubricating of thecrank pin of the center crank mounted therein, said crank and pin beingshown partly in section; Fig. 2 is a perspective view of one side of thecrank and showing, when the crank is in its lowered position, therelative position of the Wiper cup carried by the crank and of thedrip-nozzle adapted to feed lubricant to the said cup; Fig. 3 is avertical sectional View of the wiper-cup; Fig. 4 is a plan View of thesame; Fig. 5 is a 'sectional view taken on the line 5-5 of Fig. 4; Fig.6 is a vertical sectional view of the lubricant dripnozzle, being takenon the line 6--6 of Fig. 2; and Fig. 7 is a horizontal sectional viewtaken on the line 7-7 of Fig. 6.

In describing my invention, the reference numerals 2, 3, 4 and 5represent the casing, crank shaft, crank and crank pin respectively of avertical engine. Extending mto the casing 2 beneath the shaft 3 is theoil pipe or conduit 6 whichl may be connected with any suitable sourceof supply and which is provided with the drip feeder nozzle 7 whichoverhangs the receiving cup 8 carried on the crank 4, when the saidcrank is in its lowered position as shown in Figs. l and 2.

Although any suitable drip-nozzle may be employed I prefer to use thenozzle shown in the drawings, consisting of the sheet metal clip 9 whichembraces the end of the feeder pipe 6 and which is provided with thevertical duct 10 communicating with the slot 11 formed in the lower sideof the pipe 6 (see F ig. 6). The cup 8 is secured tothe crank 4 by meansof the threaded stud l2 and communicates with the oil passage way 13 ofthe crank pin 5. A diametrical blade or wiper 14 extends from within thecup a short distance above the cup mouth l5.

With the lower sweep in the revolution of the crank 4 the wiper cup 8passing beneath the drip-nozzle 7 gathers, by means of the wiper-plate14, the drops of oil that are caused to be formed on the nozzle 7, asshown by the dotted lines in Fig. 2. The oil being fed at this pointintermediate the cup 8 and the axis of rotation of the crank, it iscaused to be conveyed within the cup 8 by centrifugal tendency, where itpasses to the crank pin 5 through the duct 13. In utilizing thecentrifugal force in this manner, the oil is placed under constantpressure, effecting a perfect distribution of the lubricant.

Although the means shown are, by reason of their simplicity andcompactness, preferable, I do not desire to limit myself thereto.

The advantages of my invention will be found to reside in the fact thatI am able to provide a pressure feed without employing complicatedapparatus incident to the force feed type of lubricator.

Having thus described my invention, what I claim and desire to secure byLetters Patent is l. A lubricating system, comprising in combinationwith a rotatory element, a cup carried thereby and provided with a bladeextending diametrically therefrom toward the axis of rotation of therotatory element, and a drop feeder connected to a lubricant supply andadapted to feed lubricant to the blade at a point intermediate the bladeand the axis of rotation of the rotatory lubricant to the blade at apoint intermedi 10 ate the blade and the axis of rotation of theelement.

2. A lubricating system, comprising in rotatory element. y combinationWith a rotatory element, a cup In testimony whereof, I have hereuntocarried thereby and provided With a blade set my hand.
